The Chicago Department of Aviation is looking for a few good goats.
Chicago recently put out a bid for someone to supply goats to trim the grass at O'Hare International Airport. The bid also calls for a goat herder.
Amy Malick is the department's point person for sustainability, and she says the city is looking at a pilot program of 30 goats to eat grass and weeds in one, hard-to-mow area. She says the area is outside the security fence, so there's no danger of goats straying onto the runways.
Malick adds that the department also worries about pollution produced by mechanical mowers, so they're turning to the four-legged variety.
Atlanta recently started a similar effort, and San Francisco has been using goats for years.
